problem with punkbuster and cod 5

[stevendefour2]

i have a problem with call of duty world at war after I installed "World at War v1.1 LEVEL 65 HACK" (i'm not sure if the problem is it or another file that i have installed). the problem is this: punkbuster kick me after few seconds because of error "corrupted file memory".

I tried reinstalling the game but the problem remained.
i play only with cracked server using the method "\connect serveriport"

p.s. excuse me for my english
